Researchers of this study found good agreement between orthopedic trauma patients and their proxies at 2 weeks postoperatively with regard to estimates of preinjury function.
“Good agreement in [physical function computer adaptive test] PF CAT preinjury assessment between patients and proxies support patients’ ability to report reliable preinjury physical functioning in the early post injury setting using the PF CAT,” the authors wrote. 
During the initial postoperative follow-up, researchers asked 153 consecutive patients and their proxies to fill out the Patient Reported Outcomes Measurement Information System (PROMIS) PF CAT to assess their perceptions of the patient’s function prior to injury.
